Irule for response code

Hi All,

I am facing issue in my environment where ,f5 is modifying the response code send by server .

So if server is sending 404 ,ASM is allowing this code but when client receive this its 200 oK.

body of response code remains the same but header changes to 200 .As per our application team they need to pass header as 404 to client for some functionality to work

Any suggestion on this ,how we can solve this through irule

Regards Puluck
